SYLVANUS BARTLETT, OF HOCKING COUNTY, OHIO.

CHEESE-PRESS.

Specification of Letters Patent No. 2,469, dated February 28, 1842.

To all whomz't may concern g le it known that I, SYLvANUs BARTLETT, ofHocking county, `State of Ohio, have in-` i vented a new and usefulImprovement in machines for pressing cheese, cider, hay, 6to.. and forall other purposes where a regular, constant, and progressive vpressureis required, of which t-he following is a specification.

The frame of the press will consist of two innig-ht posts (A, A,) across piece (R) and two pieces for the sills or feet C. C.) of thefollowing dimensions: the side pieces or posts (A,) to be 10 incheswide,`1} inches thick and 2 feet and 2 inches long` and feet (C,) thefeet will be of the same thiclc ness with the posts, 4 or 5 inches wideand 2 feet and 4 inches long.

In order to render the press as light as possible, consistent with a due.regard to inserted) may be tapered down to about one fo-urth theirwidth in the middle. The cross beam or bed (B) will be 2 inches thick,10 inches wide and 2 feet and 3 inches long, and framed into the postshorizontally by double tenons, 12 or 14 inches above the lower edge ofthe feet. The space between the posts, when the frame is completed,should be 2 feet in the clear. This is all that is necessary toconstruct the frame of the press. Y

The follower (1),) (below the cross beam or bed (13)) consists of a flatpiece of timber, l() inches wide 2 inches thick and 2 feet long, so asto play up and down closely but freely between` the upright post-s. Thecheese or substance to be pressed, inclosed in a hoop (R,) with follower(L,) is intended to be placed upon this platform or follower and to belifted up so as to be compressed between said follower and the crossbeam or bed (13,) above. The two upright bars (E, E) are to be 2 inchessquare, inserted at the lowerends into the follower (l),) and passing upthrough mortises in the cross beam or bed (B) so as to fit closely, yetslide easily up and down, by means of cast iron racks (F, F) about 6 or8 inches long with 8 or 10 cogs or teeth, similar to the teeth or cogsof a common jack, and two axles (G, G) `two feetl long with a. journalat each end about Q'inches diameter turning in corresponding holes inthe posts of the frame, near the top, and with cast iron cog wheels (H,H,), 4 inches diameter to match the teeth of the racks (E, E,) the eyesof the cog wheels to be 2 inches square, the diameter of the axles orrollers (Gr, G,) between the cog wheels to be l to 6 or S inchesdiameterwith holes (I, l, I,&c.) properly arranged for the insertion ofone or more levers (J, L) 2 or 3 `feet in length, with weights (W, W,)suspended from their outer' ends. ln small presses one of the axles orrollers, &c., may be dispensed with and the upright bars kept steady intheir places by blocks or strips nailed to the inner side of the postsof the frame, opposite the remaining rack and roller (these are notattached to the model, but may be readily supplied) 5 to 8 pound weights(WV, VV,) suspended to the levers (J, J are sutlicient to press acheese, placed as before speciiied, perfectly, evenly and expeditiously,and with the greatest possible ease and convenience. To apply thisprinciple to hay and cider presses and for other purposes when continuedand progressive power is required, it will only be necessary to increasethe dimensions in the foregoing proportions, so as to secure the properstrength, and employing always two axles or rollers with theirappurtenances.

The advantages of this press are manifest, especially in the manufactureof cheese; to wit: perfect e-Xactness and evenness in the pressure uponthe cheese, or other substance, secured by the greater steadiness withwhich the movable follower or platform (D) passes up and down, thegreatest power secured and applied in the smallest space and greatestpossible convenience and the cheapness and simplicity of the whole.

lVhat l claim is- The method of constructing and arranging the followeror movable platform and upright bars in combination with the toothedrollers (G G) and weighted levers (J J), that is to say arranging thefollower or movable platform (D) below the bed of the press (by whichgreater steadiness of motion is secured) the upright bars slidingthrough openings in said bed (B) and having teeth on both sides of theminto which the toothed rollers (Gr G) are geared, the` whole beingconstructed and operating as set forth, the other parts of the press em-
